(3) Permit applications may comply with the requirements of 2.04.5(1) 2.04.6(1)(a), 2.04.6(2)(a) <br />and 2 04 7 by providing accurate descriptive and predictive information relating to geology, water quality and <br />quantity for the area to be affected over the estimated life of the operation based upon extrapolation by an expert <br />in the field from documented data on the geology, water quality and quantity of similar areas provided that the <br />data used by the expert is included within the permit application the expert opinion is approved by the Division <br />and all such data are made available to the public for review and comment. <br />RESPONSE <br />The information and analysis referenced above represents over five years of data collection in the permit and <br />adjacent area by Federal and State agencies, private organizations and universities. Conclusions and opinions of <br />experts of each field may be found in the accompanying exhibits. The conclusions and opinions were derived by <br />extrapolation of the data collected in the permit and adjacent areas. <br />RULE 2.04.6 - GEOLOGY DESCRIPTION <br />(1) General Requirements - The geology description shall include a description of the g eology <br />(stratigraphy and structure) within the proposed permit and adjacent areas. This description shall be sufficient in <br />detail to: <br />(a) Define the relationship between structural geology and the occurrence, movement, <br />qualily and quantity of potentially impacted surface and groundwater; <br />(b) Assist in determining the feasibili1y of the proposed reclamation plan; <br />(c) Assess the potential for off -site material damage to the hydrologic balance; <br />(d) Assist in the preparation of the probable hydrologic consequence statement and the <br />establishment of the hydrologic monitoring plan; and <br />(e) Assist in the preparation of the subsidence control plan under 2.05.6(6). <br />RESPONSE <br />The information required by this rule can be found in the responses provided to Rule 2.04.6 (3). The text for this <br />response starts on page 2.04 -12.1 and onto 2.04 -19. This referenced section addresses the general geology <br />discussion required by this rule. Additional information addressing the hydrologic component of this rule can <br />be found in Rule 2.04.7. The text for this rule can be found on pages 2.04 -19 through 2.04 -43. <br />In reference to the geologic information presented and the overburden characterization associated with addressing <br />the feasibility of the reclamation plan it should be noted that the TCC facilities are located next to the Colorado <br />Yampa Coal Company reclaimed surface mine. The surface mine has been successfully reclaimed and the TCC <br />surface facilities will utilize the same resources and reclamation techniques as applied to the surface mine. <br />(2) Surface Mining <br />(aa) The description shall include a general statement of the geology (stratigraphy) and <br />structure) within the proposed area to be affected over the life of the operation down to and including the first <br />aquifer and other coal seams if any, below the lowest coal seam to be mined. A geologic map with geologic <br />cross - sections of the permit area prepared in accordance with 2.10 shall accompany the descriptions and <br />include the following: <br />PR09 -08 2.04 -12 04/10/09 <br />
